页边距问题仅对scrollview的根子级造成。您可以将页边距添加到内部子级。
将android:paddingBottom

添加到父级ConstraintLayout有效。

我切换到了线性布局，约束和线性布局在这种情况下都没有帮助。我确实在线性和约束布局中添加了layout_marginBottom。按钮的

layout_marginBottom

属性正在工作。按钮下方的黑色空间是边距（请注意，您的scrollview具有黑色背景）。这里的问题可能是您的

ConstraintLayout

的高度。它的高度是0dp，将变成它孩子的高度。也许如果你把它放到“匹配父项”中，你会得到你想要的绿色背景
